Stimulus

It is repeatedly claimed that the dumping of nuclear waste poses no threat to people living nearby. If this claim could be made with certainty, there would be no reason for not locating sites in areas of dense population. But the policy of dumping nuclear waste only in the more sparsely about safety on the part of those responsible for policy.

What this question is testing

Weaken

Conclusion

The author argues: officials say nuclear dumping is safe, but they only dump in sparsely populated areas — so they must secretly have doubts about safety.

Evaluate

The reasoning is: if they really believed it was safe, location would not matter. So choosing one type of location must mean they think it is safer.

But there could be other reasons to pick sparsely populated areas. Maybe land is cheaper. Maybe permits are easier. Maybe transportation routes are simpler. Maybe the local government is more cooperative.

Imagine someone always parks their car at the back of a lot. The author would say: "They must think the front is dangerous." But maybe they just like the walk, or the back has more shade, or the front is always full. The location preference does not have to be about danger.

Goal

Find an answer giving a non-safety reason to prefer sparsely populated areas.

Which one of the following, if true, would most seriously weaken

Answer choices

  1. Opposite8% picked this

    Evacuation plans in the event of an accident could not be guaranteed to work perfectly except where

    This actually supports the author. If evacuation plans only work where population is small, that is itself a safety-related reason to choose sparsely populated areas — which means officials are picking those areas because they have safety concerns. The argument is reinforced, not weakened.

  2. Opposite9% picked this

    In the event of an accident, it is certain that fewer people would be harmed in a sparsely populated than

    This is also a safety-related reason. If accidents would harm fewer people in sparsely populated areas, then officials are choosing those areas to limit the human cost of any accident — a safety motivation. The author's conclusion that they have safety misgivings would be supported, not weakened.

  3. Correct70% picked this

    Dumping of nuclear waste poses fewer economic and bureaucratic problems in sparsely populated than in

    Why this is right

    Here is the alternative explanation. If sparsely populated areas pose fewer economic and bureaucratic problems, then officials may be choosing them for purely practical reasons — not because they have any doubts about safety. The author's inference (location choice = safety doubts) collapses, because the location choice can be fully explained by reasons that have nothing to do with safety.

    Skill tested: Weaken · how this choice captures the argument's function is the move to repeat next time.

  4. No Impact5% picked this

    There are dangers associated with chemical waste, and it, too, is dumped away from areas

    What happens with chemical waste does not establish why nuclear waste is sited where it is. Even if chemical waste is also dumped away from populated areas for safety reasons, that does not give us a reason to think nuclear officials are not similarly concerned. This neither breaks the author's inference nor offers an alternative.

  5. Opposite9% picked this

    Until there is no shred of doubt that nuclear dumps are safe, it makes sense to situate them where they pose the

    This is essentially a normative restatement of the author's position: it makes sense to be cautious until we are sure. If anything, this supports the idea that officials reasonably have safety misgivings — exactly the conclusion the author drew. It does not weaken the argument.
